  • Patent number: 11184950
    Abstract: A system and method for incorporating co-site interference impact in dynamic spectrum access for heterogeneous hierarchical networks where preprocessing is used to create lookup tables for the different types of co-site interference. The lookup tables reflect the weight of the spectral leakage lobes for all signals internal and external to the system under different conditions. Lookup tables can be used at any hierarchical entity that offer dynamic spectrum access services in a cloud services construct. Co-site interference impact becomes its own set of dynamic spectrum access services that can be added to a dynamic spectrum access capable system without impacting the other dynamic spectrum access computations needs such as computation that produce spatial separation. Co-site interference becomes a second order spatial separation that is abstracted in lookup tables and adaptable based on measured metrics such that different lookup tables can be used under different conditions.
